It is presumed that the person whose e-mail address you have (and whose postal address you want) is not a stranger to you, but is a friend or a relative with whom you have lost touch over a period of time.
It may not be possible to find out his or her postal address merely by typing in his or her e-mail address in the people search directory of a website. However, you can send this person an e-mail asking for his or her postal address.
If you and the person whose postal address you want are corresponding to each other after a long period of time, it is likely that you may have to refresh his or her memory. It is better not to be hasty in asking for his or her postal address.
